I have a Borla TD on my car, and I love the sound. It's the only reason I put it on. But now that my Z is no longer my daily driver, I wouldn't mind the exhaust note being a little louder. I figure test pipes would give me what I'm looking for. I'm an autocrosser and now that I finally have an LSD I can actually use some power gains as well. I've done some searching around and I see that most people that are running test pipes also have the magnaflow X pipe/muffler. Is there a set of resonated TPs out there that will work with my Borla with the regular H-pipe and still not give any rasp? Or should I really be looking at HFCs?

 

Can’t think of anything unique about Borla that would warrant a specific brand test pipe. Sorry.

 

Im using the Kinetix resonated test pipes with my Borla and its not raspy.

 

im using top spees pro 1 test pipes (resonated) with my borla .. not raspy ... everyone tells me it sounds exotic

 

Stillen High Flow Cats with the Borla TD exhaust was one of the best sounds I ever heard on a Z. But I realize you're looking for TP....

Wow... that video of the stilen/borla exhaust was pretty impressive. But it's hard to justify $500+ for the stillen cats vs. $150 for the test pipes... that's half a set of race tires! Matix, are those top speed test pipes you're using the same resonated pipes sold by intensepower? Have you had a CEL using them, and if so, how did you fix it?

 

I've got a set of Nvidia test pipes on along with my borla TD. I love the sound. There is a small amount of rasp for about a 250 rpm range between 2500 and 2750 rpm, honestly its so small that it really doesnt bother me. definitely not enough to warrant the extra money and work to put on the magnaflow x pipe
